A custom search engine is one that can be created by anyone. The developers can choose which websites to add to the search engine and limit the results to only those domains. The conventional way to go about it was to take a for from an existing open source project like Solr or Elastic search and then build the required features and the UI to add on a website. This was by no means an easy task and would often involve heavy developer costs.
